Anna brings us this charitable little note from the her apartment building in London, Ontario.

“Anytime Stan” — proof that Canadians really are the nicest people on earth?

Meanwhile, in Milwaukee…

And lastly, a vaguely dadaist interpretation, in what very well may be another one of L.A.’s elevator-cum-film sets.

“This isn’t quite a note,” writes Andrea in California. “Actually, it’s not a note at all.” But passive-aggressive? Yessir.

She explains: “My dad’s job is to take out the trash. It’s probably his only household chore. But for some reason, it never seems to get done.” So Andrea’s mom took action. Sort of.

After this, Andrea says, it only took her dad three days to acknowledge the trash and take it out.

Mona in Los Angeles brings us this pair of notes from her high-rise Century City office building.  Says Mona, “Apparently my co-worker saw the panties at issue. My question is…who leaves their panties in the bathroom at work?  Who does that?”

My question: Why are we letting Paris and Britney off the hook? If they actually remember to wear them, shouldn’t we encourage keeping them on?

And then there’s this one, which brings up the old mad bomber-era debate about which gender leaves the bathrooms in worse shape.

Our anonymous submitter spotted this note on a resident’s door in an apartment complex in Portland, oregon. Oddly, she says, this resident lives alone.

Meanwhile, James’s roommate found in the laundry room of his Sacramento apartment complex.

According to a 2006 Harris poll, office-workers say annoying ringtones are one of their biggest pet peeves — second only to office loud talkers. So I’m actually surprised we haven’t seen more notes like this one, which Flickr’s Heather Champ found taped to her (chirping) cell phone once upon a time.

What’s your pick for the most obnoxious ringtone award?

Writes our anonymous submitter in Corte Madera, California: “We have a lot of passive-aggressive notes up around the office, and most of them are addressed to the entire office staff in common areas. You can imagine my surprise when after eating lunch and going out for a smoke break with some coworkers today, we came back to find a bit of passive-aggressiveness on our lunch table — not 15 minutes after we had left it. Grrrrr.”

More choice guilt-trips from this office — including yet another “your mother doesn’t work here” note, follow.

Today’s tasteless gross-out is brought to us by Christina in Irvine, California. (My apologies in advance.)
